I found this video on a site called Joost which I had never heard of before. The video is called "The Way of the Samurai" and it appears to be a video from PBS. I have not had a chance to watch it yet but it looks interesting.
Update 4/9/09: Apparently this video and any others from Joost are not viewable in Japan. Sorry about that. When I was in Japan I had this same issue with the popular site Hulu.com which has full length TV shows but is not viewable in Japan as well.
